The sound quality is great for the price. I saw this and thought I should try it. It greatly exceeded my expectations. I like the Riptidz better than the JVC FX67 Air cushion which is more than double the price. The Air Cushion has a V shaped sound signature, while the Riptidz imo sounds quite balanced. It has decent bass, however I would describe the bass as being fast rather than deep. Bassheads should consider something like the Panasonic RP-HJE450 if they want more bass slam.

The Riptidz has a very open sound. It has 11mm drivers, while most IEMs under $10 have 9mm or smaller ones. It doesn't isolate so well. It is listed as being water and sweat resistant. This is my favorite IEM under $10. Those who are willing to spend around $15-20 though should imo consider the Panasonic RP-HJE355 or JVC HA-FX40.
